RegEx not working while IndexOf does... why?

I have this RegEx expression that I am trying to find in a string:

                    r = new Regex(">  $");
                    m = r.Match(bookInfo, m1.Index);
                    if (m.Success)

It doesn't find the string, yet the following does:

                index2 = bookInfo.IndexOf(">  $", m1.Index)

What is wrong with the RegEx statement?

the trailing dollar in the regex expression means "end of line"
the trailing dollar in the IndexOf call means "dollar sign"

Great!  can you tell me how to 'escape' the dollar sign so I can use it in the expression?

if you really want to match the dollar sign use:
r = new Regex(">  \$");

Will it work?

 r = new Regex("*>  $*");
